SELF-cirrus METAL BEARING.

Application filed June 19,

To all whom itmag concern:

Be it-known that LNonronW. KINNEY, citizen of the United States, residing at Haverhill, in the county of Essex and State of Massachusetts, have invented certainn'ew and useful Improvements in Self-Oiling Metal'Bearings; and'I do declare 'theafolloiw ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it 'appertains to make and use the same. 7

My invention has for its object to provide a bearingfor high speed vertical spindles,

constructed in a novel manner for effective lubrication andfor adjustment to compensate for wear, proper positioning of the spindle, etc. T

f With the foregoing in view,- the invention resides in the novel features of construction and unique association of parts'hereinafter described and claimed, reference being made to the accompanying drawings.

Figure 1 is avertical'section ofa bearing constructed in accordance with my inven-- tion.

Fig. 2 is a top plan View. s

Fig. 3 is a horizontal section on the plane indicated by the line 3-3 of Fig. 1.

Fig. 4 is a similar view on the plane of line 41 of'Fig. 1.

In the drawing above briefly described,

the numeral 1 designates an outside shell which may be supported in any preferred manner, the bore 20f said shell opening through both itsupper and lower ends. A cylindrical cup 3 is snugly though slidably received in the shell 1 and rests on a flange 4 with which a vertical adjusting screw 5 is provided, said set screw being threaded into the lower end of said shell, so that by adjusting the screw in question, the cup may be vertically shifted within the shell. Set screws or the like6 are provided for locking the cup 3 in adjusted position.

The bottom of the cup 3 is provided with a socket 7 into which a bearing disk 8 of any suitable metal is driven and held by friction, and an opening 9 may well be provided at the bottom of the socket for inserting a tool to remove said bearing disk when required. An anti-friction ball lO rests 011 the disk 8 and is received in a concave 11 formed in the lower end of the vertical spindle 12. This spindle is provided with a downwardly tapered sleeve 13 which is rotatably received in the similarly tapered .bore of a vertically p e i'; o nt- Patented July 13,1920.

adjustable bushing 14 which is in running contact with the wall of the cup 3. Between its ends, the bushing 14: is reduced in diameter to provide an external 01]. groove 15, and

Y while the reduced-upper end 19 of another set'screw 20 is received in a socket 21 in the lowerend of said bushmg for supporting the latter pr-o i'er'ly 1n the cup 3. The set screw '20 is threaded through the bottom of the cup at which it was locatedbefore any wear occurred. After the correct adjustments are made, the screws 6 and 18, and the nut 22 are again tightened. I

-The sleeve 13 bears atits upper end against a shoulder 23 on the spindle 12 and is clamped against said shoulder by a nut 24 threaded on the lower end of said spindle, and a suitable washer 25 of fiber or the like is by preference located between the upper end of said sleeve and the nut 17 said nut and washer being preferably connected by vertical dowel pins 26.

Any suitable means may be provided for supplying oil'to the cup 3, but I prefer to provide said cup with a port 37 into which piping 28 is threaded, said piping leading from an oil cup 29. A cook 30 may be provided in the bottom of the cup for draining the oil therefrom when necessary.

By constructing the bearing as shown and described, or approximately 1n this manner, it is hlghly e'fliclent and desirable for high speed vertical spindles and the lubrication is of such efficiency as to practically prevent wear. The small wear that does take place is readily compensated for by the sev- I,

shall not take place. The oil travels upwardly between the parts 13 and 14, by centrifugal force and returns through the openings 16. This circulation not only causes eflicient lubrication, but prevents overheating both of the oil and the bearing. Since probably the best results may be obtained from the details disclosed, they may; well be followed, but within the scope of the invention as claimed numerous minor changes may wellbe. made.

In avertical spindle bearing an outer V shell, a vertical cup mounted in said shell compensate for wear, a circular nut threaded in. the upper end of saidcup, and a set screw threaded through said nut and bearing. against the upper end of said bushing to hold it tightly against said raising means. 2.
